摘　　要：目的探讨声触诊组织成像量化(VTIQ)技术对桥本甲状腺炎(HT)合并甲状腺乳头状癌(PTC)颈部中央区肿大淋巴结性质判定的价值。方法回顾性分析96例经病理证实的PTC合并HT患者的132枚颈部中央区增大淋巴结的VTIQ图像,密集测量其横向剪切波速度(SWV),绘制特征性曲线(ROC),分析VTIQ技术的诊断价值。结果 132枚颈部中央区淋巴结中,PTC转移淋巴结71枚,反应性增生淋巴结61枚。PTC转移性淋巴结SWV最大值、最小值、中位数及平均值显著高于反应性增生淋巴结的SWV值(P<0.001)。据ROC分析结果,SWV平均值效能最高,其截断值为3.285 m/s、准确度为87.12%、灵敏度为90.1%、特异度为80.3%。结论 VTIQ技术在判定HT合并PTC颈部中央区增大淋巴结性质中具有一定的应用价值。Objective To investigate the value of virtual touch tissue image quantification(VTIQ)technique in the differential diagnosis of lymph nodes in central cervical zone for papillary thyroid carcinoma(PTC) complicated with Hashimoto′s thyroiditis(HT). Methods The VTIQ imaging data of 132 lymph nodes in central cervical zone in 96 PTC patients with HT confirmed by pathology were retrospectively analyzed, the shear wave velocity(SWV) of the lymph nodes was measured intensively, the receiver operating characteristic(ROC)curve was used to assess the value of VTIQ. Results 132 lymph nodes in central cervical zone included 71 metastatic lymph nodes of PTC and 61 reactive lymph nodes. The SWVmax, SWVmin, SWVmedian and SWVmean of PTC metastatic lymph nodes were significantly higher than those of reactive hyperplasia(P<0.001). According to ROC curve analysis, the SWVmean was best value for the diagnosis efficacy, the cut-off value of SWVmean was 3.285 m/s, the accuracy, sensitivity and specificity were 87.12%, 90.1%, 80.3%. Conclusions VTIQ technique has important application value in the differential diagnosis of lymph nodes in central cervical zone for PTC complicated with HT.
